B44 gearing
 

Just put a 5 turn motor in what pinion should I have on with standard spur gear currently have 19 on

Indoors or outside?

Outside I would say 22/23 to start with and check your temps!

5.5t or 5t? your about spot on 19/20 with standard 84t spur depending on the track layout, beaware I think 44.1 spur is a 81t so dont get confused with gear ratio setups with them!

What do you recomend im running indoors with 6.5, 81 spur

It's a 5 t speed passion I did have a 19 pinion on with my Hobbywing 9t so just put that pinion on it
